Treatment of a mixture of aromatic compound and ethyl α-(methylsulfinyl)acetate (5) with p-toluenesulfonic acid under continuous removal of separated water brought about an intermolecular aromaticsubstitution to give ethyl α-(methylthio)arylacetate (6). Similar treatment of acylmethyl phenethyl sulfoxide (8) led to cyclization into 1-acylisothiochroman (9).

(4) and (5) reacted mildly with aromatic compounds in the presence of Lewis acids to give the corresponding sulfides which in turn desulfurized to arylmethylene ketones, arylacetoesters, and arylacetonitriles.
